PowerShell pack: PSuserTools
The PSusertools module contains 4 functions:
get-currentuser uses System.Security.Principal.WindowsIdentitiy to identify the current user. One oddity is that the group information returns the SID of the group rather than the name. We need a SID to name translator.
Test-IsAdministrator returns true if the user is an administrator. In PowerShell this equates to running the shell with elevated privileges – good test to put in your scripts to make sure that you have the permissions to do what you need
